He has written four books on the climate-and-energy nexus, the most recent of which is The Winning of The Carbon War.  He continues to chronicle that transition and its intersection with the information revolution in a blog (, and occasional articles for national media. He advises corporations via another creation of his, The Carbon War Limited, and lectures on short courses in business and society at the Universities of Cambridge and St Gallen (Switzerland).
